📣 New paper out!
We explored how fungal infection 🍄 affects the bright warning colours of wild poison frogs 🐸. Neither melanin nor carotenoid colouration reliably signals infection status. Defensive signals may remain consistent even under pathogen pressure 👩🔬🧪

New paper out in @behavecol.bsky.social!
Multiple studies show that sexually selected traits such as colours can reflect the presence of pathogens/parasites, but, can defensive coloration do the same? L. Schlippe Justicia, @carodittrich.bsky.social, O. Nokelainen & I tackled that question (1/3)
